Memory Logging
Lonkar Spectral Analysis Tool

Maximize your results with Lonkar’s Spectral Analysis Tool; post-fracture memory logging services with the agility and cost-effectiveness of slickline and the safety of R.A. Tracer. With a high-pressure in-line injection system and non-leaching isotopes, your frac treatment can be evaluated using a single or multi isotope and an effective logging program.

Logged data can be used to determine:

  1. proppant height (sand distribution)
  2. pad height (fluid leakoff)
  3. if the fracture height is greater than desired, reducing the frac length
  4. if there any un-stimulated or poorly stimulated intervals in the reservoir

By applying proper logging tools and interpretation techniques to a post-frac analysis, much insight can be gained into the proppant placement, hydraulic height, perforation effectiveness and total contribution.

We strive to design tracing and logging programs which achieve maximum results with the least amount of cost, while coordinating involvement with the tracing company, logging company and pumping company.

Benefits of High Pressure Injection

  • Increased safety – Injection Unit is downstream of personnel and pumpers
  • Explosion-proof injection systems
  • Positioned directly in frac line, eliminating contamination of frac equipment. Certified and tested to 103.5MPa working pressure and 155.25MPa test pressure
  • Does not rely on single pumper to distribute radioactive material
  • Compatible with CO2 and acid fracs
  • Able to handle low injection rates with no residual isotope fallout in pumpers
  • No injection service personnel in treatment pumping area
  • Safety check valve ensures contents are contained before the frac and during the flush
  • Isotope is a non-leaching product that can be buried on location in accordance with CNSC regulations
